An earthquake gas valve that uses a battery powered actuation mechanism to automatically close a gas valve when the movement caused by an earthquake is perceived. A gear motor is activated by a plurality of shake switches which in turn cause a motor driven radial rack to rotate. The rack terminates in a closure plug which obstructs the gas outlet opening and prevents gas from entering the house or office when an earthquake occurs. A timing circuit delays the activation of the closure plug to make sure that the motion has been caused by an earthquake and not by an accidental brief jarring action.

Earthquake gas valve

An improved universally actuable robot assembly including a pedestal support base and a body which is swivelably mounted and rotatably driven around the base. A main support arm extends substantially horizontally from the body at a generally centralized location and terminates in a first universally swivelable member which is mounted to a first face of a vertically orientated intermediate plate member. A selected number of linearly actuable driving arms extend from the body in parallel fashion relative to the main support arm and at preselected spaced apart distances. The driving arms each include a linearly actuable cylinder for adjusting an overall length of an associated driving arm. A linearly extending engaging member is secured to and extends from a second face of the intermediate plate member and the plate member is responsive to manipulative motion of the driving arms in a universal manner about a pivot point established by the main support arm to universally position the engaging member.
